Hi,

Will it make any difference if I place the voltage divider connected to the Feedback after the capacitor (noise reduction)?

Hi Jeevan,

Moving the capacitor before the feedback loop will have impact LDO noise.

Increasing the capacitance of C2 could have a small impact on noise, however, adding an additional capacitor, in parallel with R1 (feed forward capacitor or C_FF), can reduce high frequencies noise per the app note: Pros and Cons of Using a Feedforward Capacitor.

BR,
